May 01/01 CES 3. Fault Confirmation
__________________
A. Aircraft Maintenance Configuration
(1) Open the AFT cargo compartment door (referred to as cargo door) in the normal mode (Ref. AMM TASK 52-30-00-860-001).
NOTE : Make sure that a second person does not operate the FWD cargo
____
door.
(2) Open the FWD cargo door in the normal mode (Ref. AMM TASK 52-30-00-860-001).
NOTE : Make sure that a second person does not operate the AFT cargo
____
door.
4. Fault Isolation
_______________
R **ON A/C 001-049, 101-105,
A. If the fault confirmation gives that only the AFT cargo door does not open and the ELEC PUMP-Y (3075GX) does not operate (fault in the door control system):
- do a check for 28 VDC between: the RELAY-TIME (6MJ) connector A/B1 and GND (Ref. ASM 52-35/01).
NOTE : Make sure that the selector of the manual selector valve 2504MJ is
____ set to OPEN during the fault isolation procedure.
(1) If there is 28 VDC:
- do a check for 28VDC between the RELAY-TIME (6MJ) connector A/C1 and GND (Ref. ASM 52-35/01).
(a) If there is 28 VDC:
- do a check for 28 VDC between: the RELAY-TIME (6MJ) connector A/X1 and GND (Ref. ASM 52-35/01).
1 If there is 28 VDC:
_
- replace the RELAY-TIME (6MJ).
(b) If there is no 28 VDC:
- do a check for for 28 VDC: the RELAY-L/G POSITION, SYS 2 (12GB) connector A/D1 and GND (Ref. ASM 52-35/01).
1 If there is 28 VDC:
_
- do a check for continuity: the RELAY-L/G POSITION, SYS 2 (12GB) connector A/D1 and A/D2 (Ref. ASM 52-35/01).

May 01/05 CES 2 If there is continuity:
_
- do a check and repair the wiring as necessary between: the RELAY-TIME (6MJ) connector A/C1 and the RELAY-L/G POSITION, SYS 2 (12GB) connector A/D2 (Ref. ASM 52-35/01).
